I-A2-70 yenziwe ngani?
I-A2-70 yenziwe ngani umbuzo ojwayelekile embonini yamakhemikhali nasezintweni zokubopha. Ukuqonda impahla, izakhiwo kanye nokusetshenziswa kwe-A2-70 kubalulekile ukuze uqinisekise impumelelo yephrojekthi yakho. Kulesi sihloko, sizohlinzeka ngemininingwane eningiliziwe yencazelo yezinto ezibonakalayo, ukwakheka, kanye nezakhiwo ze-A2-70 kanye nokusetshenziswa kwayo ezimbonini ezahlukahlukene.
Incazelo Eyisisekelo Yento engu-A2-70
I-A2-70 ibhekisela ekucacisweni kwensimbi engagqwali ye-austenitic evame ukusetshenziswa kuzibopheli ezifana namabhawudi, amantongomane nezikulufu.I-A2 imele uhlobo lwezinto ezibonakalayo, kuyilapho u-70 ebonisa isilinganiso sawo samandla aqinile. Ngokukhethekile, impahla ye-A2-70 ihambisana nezinga le-ISO 3506 lamazwe ngamazwe lamabanga ensimbi engagqwali, futhi inezakhiwo ezinhle kakhulu ikakhulukazi mayelana nokumelana nokugqwala namandla emishini.
Ukwakheka kwamakhemikhali kwe-A2-70
I-A2-70 impahla iwela ngaphansi kwesigaba sensimbi engagqwali engu-304, enezingxenye eziyinhloko ezihlanganisa insimbi, i-chromium (18%), i-nickel (8%), nenani elincane lekhabhoni (isilinganiso esiphezulu esingu-0.08%). Ukwakheka kwamakhemikhali kwale alloy kuyinikeza ukumelana nokugqwala okuhle namandla emishini. Ikakhulukazi, ukungezwa kwe-chromium kwakha ifilimu yokuzivikela eminyene ye-chromium oxide, evimbela ngokuphumelelayo i-oxidation nokugqwala. Ingxenye ye-nickel, ngakolunye uhlangothi, inyusa i-ductility kanye nokuqina kwento, ithuthukise ngokwengeziwe amandla ayo okusetshenziswa ezindaweni ezinokhahlo.
Izakhiwo Zemishini ye-A2-70
Izakhiwo zemishini ziyisici esibalulekile ekuqondeni ukuthi i-A2-70 yenziwe ngani, njengoba i-A2-70 inamandla aqinile okungenani angu-700 MPa, okuyilapho i-“70″ ivela khona. Ngaphezu kwalokho, i-A2-70 inokumelana okuhle kokugunda, i-ductility namandla okukhathala. Lezi zakhiwo zenza i-A2-70 ibe ilungele ukwakhiwa kwama-high-strees adinga amandla ashukumisayo, ikakhulukazi amandla ashukumisayo.
Izindawo zokufaka izicelo ze-A2-70 material
Ngenxa yokumelana nokugqwala okuhle kakhulu kanye nezakhiwo zemishini, impahla ye-A2-70 isetshenziswa ezimbonini eziningi, ikakhulukazi emikhakheni yamakhemikhali, yasolwandle, yokwakha kanye neyokucubungula ukudla. Embonini yamakhemikhali, i-A2-70 ivamise ukusetshenziswa emishinini nasezinhlelweni zamapayipi ezidinga ukumelana namakhemikhali abolayo. Ukumelana nokugqwala kwe-A2-70 kugqame ikakhulukazi ezindaweni zasolwandle, okuyenza ifanelekele ukusetshenziswa ekwakhiweni kwemikhumbi, amapulatifomu kawoyela aphesheya kwezilwandle, nezinye izinhlelo zokusebenza ezidinga ukumelana nokugqwala kwamanzi olwandle.
Izinzuzo kanye nokubi kokuhlaziywa kwempahla ye-A2-70
Uma kuqhathaniswa nezinye izinto zensimbi engagqwali, i-A2-70 inezinzuzo eziningi, njengokumelana nokugqwala okuhle, amandla aphezulu emishini kanye nohlu olubanzi lwezinhlelo zokusebenza. Iphinde ibe nemikhawulo ethile.I-A2-70 ayifanele ukusetshenziswa ezindaweni ezine-chloride ion ephezulu, njengoba lokhu kungase kuholele ekugqwaleni komgodi. Inokumelana nezinga lokushisa eliphansi futhi ayifanele ukusetshenziswa ezindaweni ezishisa kakhulu zokushisa.
Isifinyezo
Impendulo yombuzo wokuthi i-A2-70 yenziwe ngani ukuthi i-A2-70 iyinsimbi ye-austenitic engagqwali esekelwe ku-304 yensimbi engagqwali, enokumelana nokugqwala okuhle namandla emishini, futhi isetshenziswa kabanzi emikhakheni eminingi efana nezimboni zamakhemikhali, zasolwandle, nezokwakha. Ukuqonda izakhiwo ezibonakalayo nezimo zokusetshenziswa ze-A2-70 kusiza ukwenza ukukhetha okunolwazi kakhudlwana kumaphrojekthi wobunjiniyela.
Ngesethulo salesi sihloko, ngikholwa ukuthi unokuqonda okujulile kwempahla ye-A2-70, ehlinzeka ngolwazi olubalulekile ezinqumweni zephrojekthi yesikhathi esizayo.
